IMG 1010 - Overview of VoIP

Overview

An IMG can perform a two-way conversion between circuit-switched data (TDM) and packet-switched data (VoIP). A conversion is required if going from circuit switched data (TDM) to packetized voice applications such as the Voice over Internet Protocol (VoIP). Circuit-switched voice is converted to IP packets using compression algorithms that can increase capacity toward the IP network side. An IMG can also integrate media resources over IP technology. One of the benefits offered by the IMG is that it supports modifying the parameters of an individual call while the call is active. This enables capabilities such as being able to change the quality of service without losing a call.
